Application April 26, 1945, Serial No. 590,458 6 Claims. (01. 62-447) My invention relates to a new and usefulmanufacture, i. e., a protective collar andoverflow bracket, made of cast iron or other suitable material, for use in connection with spiral cooler coil such as are commonly used by taverns for the accompanying drawing, and particularly cooling liquids or beverages and which make use The present invention'remedies this objectionable condition by the provision of a flanged protective collar unit that willprevent the coil from slipping up within the cooling chamber andwill prevent its lower portions from being damaged in the course of manually packing ice down into the surrounding ice chest or chamber.

The objects of my invention are (1) By means of the protective, flanged collar securely, though adjustably, set into and over the top or rim of cylindrical sleeve of the standard types of coil refrigeration units common to liquid dispensing apparatus, to prevent damag and distortion to the coil pipe when filling the tank with ice and when packing ice into the ice chest or icing chamber.

(2) By means of a bracket adjustably attached to the wall of cooling chamber, or, in the alter.- native attached to faucet shank, and slipped into and through an oblong slot of an integral extension of the protective collar, to maintain the cylindrical sleeve and spiral coil unit in upright proper position and the mounting bracket thereof above overflow level. 1

pointed out in th appended claims.

Referring now to the drawing:

Fig. 5 is a detail cross section of said bracket,

:viewed on line 5-5 of Fig. 4.

7 Fig.6 is a longitudinal section of my invention showing alternative means of connecting said mounting bracket tothe faucet shank, and showing a rubber bushing mounted on the top end of the coilleading to dispensing faucet.

Similar characters refer to similar parts in the several figures of the drawing.

Referring to Fig. 1, reference character I I designatesthe' top-side or upper flange of the pro tective collar with integral flange l2 extending .downward from inner perimeter of said collar,

which collar is fitted into and over the top of cylindrical metal sleeve 24 of the spiral coil cooling unit 29.

The upper bracket-end 13, which is preferably integral; .is connected to wall IQ of ice chest or box and the lower depending bracket section .I 4 is slidably mounted in position through (3) By means or a rubber bushing set into a small round aperture and seat of an integral extension of the collar, to hold rigid and solid, and keep from distortion and displacement, the .upper. coil pipe sections leading into and connecting with the dispensing faucet.

With the above mentioned and other objects in view, my invention consists in the novelty of its concept, and in its simplicity of construction and of installation. Other and further objects and advantages of my invention, its arrangement; and combination of parts. will appear from the following description, taken in connection with slot it formed in inwardly extending ring member H, which is integral with said collar unit. The coil terminal or end section 20 leading to faucet extends through aperture, !5 of ring member H which, as stated, is integral with said collar unit and said coil end section is preferably held rigid within said aperture I5 by means of rubber bushing it set in the aperture of said ring extension l'l.

Through orifices in said bracket as shown at 22 of Fig. 3 accommodate screw or other fastening elements 22 for secure attachment of the bracket to the wall of the icing chamber, as shown in Fig. 1.

In a modified form of mounting bracket illustrated in Figs. 4 and 6, reference numeral l3-b designates a metal shank portion thereof which is equivalent to the apertured mounting portion described with reference to Figs. 1 and 3. Said mounting bracket portion I 3-17 is provided with a relatively large aperture or passage 13-11. which is of sufiicient size to be slipped and mounted upon the inwardly extending threaded nipple-like portion 25 of a conventional fitting 26 shown partially in cross section in Fig. 6. Sad fitting 26 is mounted in the conventional manner in a suitable passage through the side wall of the ice chest and it is normally secured therein by a suitable lock nut 2| threaded on the inwardly extending nipple portion thereof. The inwardly extending portion 25 of the said fitting 26 terminates in a cone seat which is adapted to receive and be engaged by a suitable bushing 21 which is held in normally secured position by lock nut 28 as shown in cross section in Fig. 6. The said bushing 21 is securely mounted about the inwardly extending end or terminal section of the coil pipe 20 which is removably held in sealing engagement in said nipple portion 25 by said nut 28.

In the mounting of the adjustable bracket illustrated in Figs. 4 and 6, either on old or new coil box installations, it is only necessary to disconnect and withdraw the terminal section of the coil pipe 20 and remove the lock nut 2| and then mount the shank portion I3b upon and about the nipple portion 25 and replace and tighten the lock nut 2| and reconnect the coil pipe section 20 by remounting the nut 28 to tightened position as illustrated in Fig. 6. The off-set or angular intermediate portion of said bracket maintains the depending lower portion M in a, position sufliciently spaced from the ice box wall so as to provide ample space for the laterally extending flange H and guard ll of the protective unit. As shown at 23 of Fig. 5, the

backside of upper portion I3-b of faucet shank bracket is providedwith two ribs running opposite and parallel to each other along the edge thereof to secure a tighter hold and to prevent distortion, as bracket backside is pressed against inner side of the ice box wall.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit or scope of the invention as claimed hereinafter.

Having thus described the invention, what is claimed as new is:

1. A protective collar of substantially right angled cross section adapted to seat within and to cover the upper end section of a cooling coil, said collar having an integral inwardly extending projection provided with a slot-like aperture for the reception of the depending portion of a mounting bracket.

2. A protective metal collar having an integral inwardly extending projection provided with two spaced apart apertures therein, one of said apertures being adapted to receive the lower end portion of a mounting bracket, and the other of said apertures being adapted to receive and hold in proper position a coil pipe terminal connecting with the liquid dispensing faucet.
